Final answer:
Alpha satellite DNA is found near the telomeres of chromosomes, protecting them and ensuring stability during cell division with the help of the enzyme telomerase.
Step-by-step explanation:
The noncoding DNA found near the telomeres of the chromosomes is satellite DNA, specifically (D) alpha satellite DNA. Telomeres consist of noncoding repetitive sequences that do not encode for proteins but are critical for protecting the chromosome ends from deterioration or fusion with neighboring chromosomes. In humans, telomeric DNA is composed of a six base-pair sequence, TTAGGG, repeated numerous times. The enzyme telomerase plays a crucial role in maintaining these telomere sequences by adding the TTAGGG repeats to the ends of chromosomes, thus preventing loss of genetic information through successive cell divisions.
